[0035] The objects, specific advantages, and novel features of the present invention will become more apparent from the following detailed description and preferred embodiments taken in conjunction with the accompanying drawings. In this specification, when reference numerals are given to components in each drawing, it should be noted that, as far as possible, identical components are given the same numerals even if they are shown in different drawings. Furthermore, terms such as "first," "second," etc. are used to distinguish one component from another, and the components are not limited by these terms. In the following description of the present invention, detailed descriptions of related known technologies that may unnecessarily obscure the gist of the present invention will be omitted.

[0036] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0037]

[0038] FIG. 1 is an exploded perspective view of a rotation mechanism for a helmet according to an embodiment of the present invention, and FIGS. 2 to 6 are side views and enlarged views illustrating a process in which a helmet equipped with a rotation mechanism for a helmet according to an embodiment of the present invention operates.

[0039] As illustrated in FIGS. 1 to 6, a rotation mechanism for a helmet according to the present embodiment is provided in a helmet including a helmet body (10), a chin guard (20) rotatably coupled to the helmet body (10), and a peak (30) rotatably coupled to the helmet body (10), wherein the chin guard (20) rotates between a first predetermined position and a second predetermined position, the peak (30) rotates between the first position and the second position, and when the chin guard (20) rotates from the first predetermined position toward the second predetermined position, the peak (30) rotates from the first position toward the second position, and when the chin guard (20) rotates from the second predetermined position toward the first predetermined position, the peak (30) rotates from the second position toward the first position.

[0040]

[0041] Basically, the helmet body (10) serves to protect the wearer's head. This helmet body (10) may be formed of a material capable of absorbing impact. For example, the helmet body (10) may include an outer shell formed of a hard synthetic resin or the like, which has high strength, and an absorbent body formed of expanded polystyrene (EPS) or the like, which has appropriate strength and elasticity, and which is placed inside the outer shell. The absorbent body may be provided with pads or the like to enhance the stability of wearing.

[0042] In addition, the chin guard (20) serves to protect the wearer's chin, and can be extended in an arc shape so that it can be placed in front of the wearer's chin as a whole. At this time, the chin guard (20) is rotatably connected at both ends to both sides of the helmet body (10), and can rotate between a first predetermined position and a second predetermined position. For example, the first predetermined position may refer to a position (Full Face Mode) when the chin guard (20) is placed in front of the wearer's chin (see FIG. 2a), and the second predetermined position may refer to a position (Open Mode) when the chin guard (20) is placed above the helmet body (10) (see FIG. 4a).

[0043] In addition, the peak (30) is provided on the upper front side of the helmet body (10) (for example, the upper side of the shield (40)) and serves to block sunlight, rain, etc. Here, the peak (30) is rotatably coupled to both sides of the helmet body (10), rotates with respect to the helmet body (10), and is rotatably rotatable between a first position and a second position. For example, the first position may mean a position where the peak (30) is positioned directly above the opening (13) of the helmet body (10) (see FIG. 2a), and the second position may mean a position when the peak (30) is positioned above the helmet body (10) (see FIG. 3a).

[0044] And, the shield (40) serves to open and close the opening (13) formed at the front of the helmet body (10), and is rotatably coupled to both sides of the helmet body (10), rotates with respect to the helmet body (10), and is rotatably rotatable between a third position and a fourth position. For example, the third position may mean a position where the shield (40) closes the opening (13) (see FIG. 8), and the fourth position may mean a position where the shield (40) opens the opening (13) (see FIGS. 9 to 10).

[0045] The above-described chin guard (20), peak (30), and shield (40) are controlled to rotate by a rotation mechanism for a helmet according to the present embodiment. Hereinafter, the rotation mechanism for a helmet according to the present embodiment will be described in detail.

[0046]

[0047] As illustrated in FIGS. 2A to 3A, when the chin guard (20) is rotated from the first predetermined position toward the second predetermined position, the peak (30) can be rotated from the first position toward the second position. For example, when the chin guard (20) is rotated upward (in the direction of the second predetermined position) from the front of the wearer's chin (the first predetermined position), the peak (30) can be rotated upward (in the direction of the second position) from directly above the opening (13) (the first position). Specifically, as illustrated in FIGS. 2B to 3B, a first connecting portion (205) may be formed on the peak (30), and a second connecting portion (207) may be formed on the chin guard (20) to be coupled to the first connecting portion (205). Accordingly, when the chin guard (20) is rotated from the first predetermined position to the second predetermined position, the second connecting portion (207) of the chin guard (20) is connected to the first connecting portion (205) of the peak (30), so that the peak (30) can be rotated from the first position to the second position together with the chin guard (20). Here, the first connecting portion (205) can be formed as a groove, and the second connecting portion (207) can be formed as a protrusion inserted into the groove. That is, when the protrusion (second connecting portion (207)) of the chin guard (20) is inserted into the groove (first connecting portion (205)) of the peak (30), the peak (30) can be rotated together with the chin guard (20). More specifically, the protrusion (second connecting portion (207)) of the chin guard (20) may protrude more in the direction (clockwise in the drawing) in which the chin guard (20) rotates from the first predetermined position to the second predetermined position. Accordingly, the end (most protruding end) of the protrusion (second connecting portion (207)) of the chin guard (20) may be caught in the groove (first connecting portion (205)) of the peak (30), so that the rotational force of the chin guard (20) may be effectively transmitted to the peak (30).

[0048] Conversely, as illustrated in FIGS. 4A to 5A, when the chin guard (20) is rotated from the second predetermined position toward the first predetermined position, the peak (30) can be rotated from the second position toward the first position. For example, when the chin guard (20) is rotated from the upper side (the second predetermined position) of the helmet body (10) toward the lower side (the first predetermined position), the peak (30) can be rotated from the upper side (the second position) of the helmet body (10) toward the lower side (the first position). At this time, a frictional force of a predetermined value acts between the chin guard (20) and the peak (30), so that when the chin guard (20) is rotated downward, the peak (30) can also be rotated downward.

[0049]

[0050] More specifically, when the chin guard (20) is rotated from the first predetermined position to the second predetermined position by a first predetermined angle (A), the peak (30) is rotated from the first position to the second position (see FIGS. 2a to 3a), and when the chin guard (20) is further rotated to exceed the first predetermined angle (A), the peak (30) can be stopped at the second position (see FIGS. 3a to 4a). For example, as shown in FIGS. 2A to 3A, when the chin guard (20) is rotated upward (in the direction of the second predetermined position) from the front of the wearer's chin (the first predetermined position)) to the first predetermined angle (A), the peak (30) is rotated from directly above the opening (13) (the first position) to the upper side (the second position) of the helmet body (10), but as shown in FIGS. 3A to 4A, when the chin guard (20) is rotated beyond the first predetermined angle (A), the peak (30) can be stopped at the upper side (the second position) of the helmet body (10) (at this time, the protrusion (the second connecting portion (207)) of the chin guard (20) can be separated from the groove (the first connecting portion (205)) of the peak (30; see FIG. 4B). That is, when the chin guard (20) is rotated upward to the first predetermined angle (A), the peak (30) is rotated together with the chin guard (20), but when the chin guard (20) is rotated beyond the first predetermined angle (A), the peak (30) is not rotated together with the chin guard (20) and is stopped at the second position.

[0051] Conversely, when the chin guard (20) is rotated from the second predetermined position to the first predetermined position by a second predetermined angle (B), the peak (30) is rotated from the second position to the first position (see FIGS. 4a to 5a), and when the chin guard (20) is further rotated to exceed the second predetermined angle (B), the peak (30) can be stopped at the first position (see FIGS. 5a to 6a). For example, as shown in FIGS. 4A to 5A, when the chin guard (20) is rotated from the upper side (second predetermined position) of the helmet body (10) to the lower side (in the direction of the first predetermined position) to a second predetermined angle (B), the peak (30) is rotated from the upper side (second position) of the helmet body (10) to just above the opening (13) (first position), but as shown in FIGS. 5A to 6A, when the chin guard (20) is rotated beyond the second predetermined angle (B), the peak (30) can be stopped just above the opening (13) (first position). That is, when the chin guard (20) rotates downward to a second predetermined angle (B), the peak (30) rotates together with the chin guard (20), but when the chin guard (20) rotates beyond the second predetermined angle (B), the peak (30) does not rotate together with the chin guard (20) and is stopped at the first position.

[0052]

[0053] As illustrated in FIG. 1, a rotation mechanism for a helmet according to the present embodiment includes a base member (15) provided on both sides of a helmet body (10), both ends of a chin guard (20) are rotatably coupled to the base member (15), both ends of a shield (40) are rotatably coupled to both ends of the chin guard (20), and both ends of a peak (30) can be rotatably coupled to both ends of the chin guard (20). At this time, the base member (15), the chin guard (20), the shield (40), and the peak (30) can be arranged in that order, and the chin guard (20), the shield (40), and the peak (30) can be rotated based on the rotation axis (17) of the base member (15).

[0054] Specifically, a first through hole (21) is formed at both ends of the chin guard (20), and a rotation axis (17) of the base member (15) is inserted into the first through hole (21), so that the chin guard (20) can rotate around the rotation axis (17) of the base member (15). In addition, a protrusion (23) protruding outward is formed at the boundary of the first through hole (21) of the chin guard (20), and this protrusion (23) of the chin guard (20) can pass through the second through hole (41) formed at both ends of the shield (40) and protrude outward from the shield (40). And, a third through hole (31) is formed at both ends of the peak (30), and a screw (33) is inserted through the third through hole (31), so that the screw (33) is fastened to the rotation axis (17) of the base member (15), whereby both ends of the peak (30) can be pressed inward (toward the chin guard (20)). As illustrated in Fig. 7, by pressing the screw (33), both ends of the peak (30) (e.g., a washer of the peak (30)) can come into contact with the protrusion (23) of the chin guard (20).

[0055]

[0056] As described above, when the chin guard (20) rotates, the peak (30) can rotate together with the chin guard (20) and then stop at the first position or the second position. To this end, as illustrated in FIG. 1, a first guide portion (100) may be formed on the base member (15) of the helmet body (10), and a second guide portion (200) may be formed on the peak (30). At this time, when the second guide portion (200) of the peak (30) comes into contact with the first guide portion (100) of the helmet body (10), the rotation of the peak (30) can be limited between the first position and the second position. Specifically, the first guide portion (100) of the helmet body (10) includes a first contact portion (110) and a second contact portion (120), and when the peak (30) is in the second position, the second guide portion (200) comes into contact with the first contact portion (110), so that the rotation of the peak (30) can be limited. For example, when the chin guard (20) is rotated upward (toward the second predetermined position) from the front of the wearer's chin (the first predetermined position) to the first predetermined angle (A) (see FIGS. 2 and 3), the peak (30) is rotated from directly above the opening (13) (the first position) to the upper side (the second position) of the helmet body (10), and when the chin guard (20) is rotated beyond the first predetermined angle (A) (see FIGS. 3 and 4), the second guide portion (200) comes into contact with the first contact portion (110), and the peak (30) can be stopped at the upper side (the second position) of the helmet body (10). In addition, when the peak (30) is at the first position, the rotation of the peak (30) can be limited when the second guide portion (200) comes into contact with the second contact portion (120).For example, when the chin guard (20) is rotated from the upper side (second predetermined position) of the helmet body (10) to the lower side (in the direction of the first predetermined position) to the second predetermined angle (B) (see FIGS. 4 to 5), the peak (30) is rotated from the upper side (second position) of the helmet body (10) to just above the opening (13) (first position), but when the chin guard (20) is rotated beyond the second predetermined angle (B) (see FIGS. 5 to 6), the second guide part (200) comes into contact with the second contact part (120), and the peak (30) can be stopped just above the opening (13) (first position).

[0057] As illustrated in FIG. 1, the first contact portion (110) and the second contact portion (120) of the first guide portion (100) may be formed in the form of protrusions protruding from the base member (15) of the helmet body (10) in the direction of the peak (30) (outward direction), and at this time, the first contact portion (110) and the second contact portion (120) may be spaced apart from each other at a certain angle with respect to the rotation axis (17). In addition, the second guide portion (200) may be formed in the form of protrusions protruding from both ends of the peak (30) in the direction of the base member (15) of the helmet body (10) (inward direction). Accordingly, the second guide portion (200) formed on the peak (30) can rotate in the space between the first contact portion (110) and the second contact portion (120) formed on the base member (15) of the helmet body (10), and as a result, the peak (30) can be restricted from rotating when the second guide portion (200) comes into contact with the first contact portion (110) or the second contact portion (120).

[0058]

[0059] Meanwhile, when viewed from the outside to the inside, the peak (30), shield (40), chin guard (20), and helmet body (10, base member (15)) may be arranged in this order. At this time, the second guide portion (200) formed in the peak (30) should not interfere with the chin guard (20) and shield (40) and should be in contact with the first guide portion (100) formed in the helmet body (10, base member (15)), so that a guide area (210) through which the second guide portion (200) passes may be formed in the chin guard (20), and an auxiliary guide area (215) through which the second guide portion (200) passes may be formed in the shield (40). As illustrated in FIG. 3a, the angle formed by the two ends of the guide area (210) formed on the chin guard (20) with respect to the rotation axis (17) and the angle (β) formed by the two ends of the auxiliary guide area (215) formed on the shield (40) with respect to the rotation axis (17) may be greater than the angle (α) formed by the first contact portion (110) and the second contact portion (120) with respect to the rotation axis (17) (β>α). Therefore, as illustrated in FIGS. 3 and 4, even after the rotation of the peak (30) is restricted by the second guide portion (200) coming into contact with the first guide portion (100, the first contact portion (110) or the second contact portion (120)), the chin guard (20) or the shield (40) can continue to rotate. In this way, after the rotation of the peak (30) is limited, if the chin guard (20) or shield (40) continues to rotate, the second guide part (200) of the peak (30) can move relatively to the guide area (210) of the chin guard (20) or the auxiliary guide area (215) of the shield (40).

[0060] As illustrated in FIG. 1, a guide protrusion (220) protruding in the direction of the base member (15) of the helmet body (10) (inward) may be formed on the peak (30), and a guide groove (225, or guide hole) into which the guide protrusion (220) is inserted and extended in an arc shape may be formed on the chin guard (20) and the shield (40). As described above, after the rotation of the peak (30) is limited, when the chin guard (20) or the shield (40) continues to rotate, a relative rotation occurs between the peak (30) and the chin guard (20) or the peak (30) and the shield (40). At this time, the guide protrusion (220) formed on the peak (30) can stably support the peak (30) while moving relatively to the guide groove (225, or guide hole) formed on the chin guard (20) and the shield (40).

[0061] For reference, a first coupling portion (205) may be formed as a groove on the inner side of the second guide portion (200) of the peak (30), and a second coupling portion (207) may be formed as a protrusion on the guide area (210) of the chin guard (20). As described above, by coupling the first coupling portion (205) of the peak (30) and the second coupling portion (207) of the chin guard (20), the peak (30) may rotate together with the chin guard (20).

[0062]

[0063] Meanwhile, as illustrated in FIG. 7, the peak (30) is pressed against the protrusion (23, protruding outward from the shield (40)) of the chin guard (20) that passes through the shield (40) by the pressing force of the screw (33), so that no frictional force is applied between the peak (30) and the shield (40). Accordingly, as illustrated in FIGS. 8 and 9, when the shield (40) is rotated, the peak (30) can be stopped in place without being rotated together with the shield (40). As a result, the wearer can open and close the shield (40) without the peak (30) being rotated.

[0064]

[0065] Additionally, as illustrated in FIG. 1, the chin guard (20) can be rotated about the rotation axis (17) by inserting the rotation axis (17) of the helmet body (10, base member (15)) into the first through-hole (21), and the shield (40) can be rotated about the protrusion (23, coaxial with the rotation axis (17)) of the chin guard (20) by inserting the protrusion (23) of the chin guard (20) into the second through-hole (41). Consequently, the shield (40) can be rotated about the chin guard (20). At this time, one or more guide means (300) may be provided to guide the rotation of the shield (40) with respect to the chin guard (20). As a result, the chin guard (20) and the shield (40) can be rotated independently of each other. However, as illustrated in FIGS. 9 and 10, when the shield (40) is in the fourth position (the position where the opening (13) is opened), and the chin guard (20) is rotated to the second predetermined position (the position when the chin guard (20) is positioned above the helmet body (10), the shield (40) is coupled to the chin guard (20). For example, a fastening portion (400) is formed at the central lower portion of the shield (40) and the central upper portion of the chin guard (20), so that the shield (40) and the chin guard (20) can be coupled by the fastening portion (400). In this way, after the shield (40) is coupled to the chin guard (20), as illustrated in FIG. 11, when the chin guard (20) is rotated from the second predetermined position (the position when the chin guard (20) is positioned above the helmet body (10)) to the first predetermined position (the position when the chin guard (20) is positioned in front of the wearer's chin), the shield (40) can be rotated from the fourth position (the position where the opening (13) is opened) to the third position (the position where the shield (40) closes the opening (13). Meanwhile, the fourth position of the shield (40) may be various positions that open the opening (13). For example, the position before the shield (40) is coupled to the chin guard (20) and the position after the shield (40) is coupled to the chin guard (20) may be different.However, the fourth position of the shield (40) does not necessarily have to be a variety of positions, but may be a single specific position (the position before / after the shield (40) is combined with the chin guard (20) may be the same).
